| چکیده | ||
| In this study, the microstructural evolutions, formed phases, micro- and macro-hardness changes and shear properties were evaluated in the as-cast, homogenized, cold-rolled and annealed AlCoCrFeNi2.1 eutectic high-entropy alloy (EHEA). These studies were carried out using X-ray fluorescence (XRF), scanning electron microscopy (SEM), Rockwell C and Vickers hardness testing as well as shear punch testing (SPT). The microstructure after cold rolling followed by annealing was consisted of an elongated phases/grains in the direction of cold rolling and in almost equiaxed phases/grains. The homogenized specimen has the minimum amounts of hardness and yield/ultimate shear strength. Due to the presence of both elongated and equiaxed structures in the cold-rolled and annealed sample, the hardness and yield/ultimate shear strength of this specimen is between that of as-cast and homogenized cases. | ||
